Obviously there's spoilers! So if you pass the GIF and see something you don't like you've only got yourself to blame.

The scene (via elcorreo.com and Watchers on the Wall) shows Tyrion Lannister and Davos Seaworth meeting while preparing a boat. Now, these two are currently supporting Daenerys and Jon respectively, so there may be some friction there. However Tyrion was also behind the Wildfire attack that killed Davos' son so... that's awkward.

Also apparently spotted at the same location but yet to be captured on film is Joe Dempsie who plays Gendry. If he's back after several seasons absence there's a lot of how and why to be answered there.
